Angles Inside the Circle Theorem:
If two chords intersect
inside a circle, then the measure of each angle is one half the
sum of the measures of the arcs intercepted by the angle and its vertical angle.

Angles Outside the Circle Theorem:
If a tangent and a secant, two tangents or two secants intersect
outside a circle, then the measure of the angle formed is one half the
difference of the measures of the intercepted arcs.
